Can chiropractic manipulation cause stroke? - The Stroke Blog
Since this story hit the news media last week, several blog readers have inquired into whether neck manipulation can result in stroke. To summarize (and what I know is what the media is reporting – this is my disclaimer), Jeremy Youngblood, a 30 year old man in Oklahoma, died from complications of a cerebellar stroke following a visit to his chiropractor. While the media has not directly stated that Youngblood sustained a vertebral artery dissection, or a tear in the lining of the artery, this has been implied. The vertebral arteries (there are typically two – one on each side, traveling within openings through the vertebrae of the neck) supply blood to the brainstem and the cerebellum, which controls balance and coordination. Spinal fluid produced in the brain drains through a canal, called a ventricle, near the cerebellum. If a vertebral artery dissection occurs, inflammation occurs at that site in the blood vessel wall, and platelets begin to collect in that area. These platelet-rich clots then can break loose and travel to the brainstem and/or cerebellum, blocking blood flow to those sites, and resulting in ischemic stroke. The danger in cerebellar stroke is that if swelling occurs in the area of damage …
